Methods and Systems for Slide Processing

1. A system for processing microscope slides, comprising: a carriage for supporting a first slide, said carriage configured to move the first slide into a position to be accessed by a slide positioner; said slide positioner including a slide clamp; processing circuitry configured upon receiving a user prompt to cause the slide positioner to obtain the first slide from the carriage and adjust positioning of the first slide, including from the carriage to a second position under a sled, and from the second position to a third position between a lens and a light source; an image capture unit comprising an imaging device configured to capture an image of the first slide in the third position; a slide dispenser unit including the sled positioned at a downward angle, configured to dispense a second slide down the sled such that a leading edge of the second slide contacts an upper surface of the first slide at or about at the angle to smear a sample on the first slide, wherein the sled includes a pivot point configured to extend towards a centerline of the second slide to cause the second slide to rock about a center point thereof when the second slide is in contact with the first slide; and wherein the processing circuitry is configured to: identify a location on the first slide where there is a layer of cells of the sample; and capture one or more images of the layer of cells using the image capture unit.

2. The system of claim 1, wherein the processing circuitry is configured to identify the location of the layer of cells based on an amount of light passing through the first slide and the sample.

3. The system of claim 2, wherein the processing circuitry is configured to compare the amount of light passing through the first slide and the sample to an amount of light passing through a portion of the first slide without the sample to identify the location of the layer of cells.

4. The system of claim 3, wherein the processing circuitry is configured to identify the location of the layer of cells based on the amount of light passing through the first slide and the sample, being a defined percentage of the amount of light passing through the portion of the first slide without the sample.

5. The system of claim 4, wherein the defined percentage is about 57%.

6. The system of claim 3, wherein the slide positioner is configured to adjust the position of the first slide to permit the image capture unit to measure light from the light source passing through the portion of the first slide without the sample.

7. The system of claim 6, wherein the processing circuitry is configured to measure light passing through the portion of the first slide without the sample at multiple locations.

8. The system of claim 6, wherein the slide positioner is configured to adjust the position of the first slide to permit the image capture unit to measure light from the light source passing through the first slide and the sample.

9. The system of claim 2, wherein the slide positioner is configured to adjust the position of the first slide based upon a measurement of the amount of light passing through the first slide and the sample.

10. The system of claim 1, wherein the layer is a monolayer of cells, and the image capture unit is configured to capture a plurality of images of the monolayer of cells in a mosaic fashion.

11. The system of claim 1, wherein the processing circuitry is further configured to identify a location of the upper surface of the first slide between the lens and the light source, and wherein the location of the upper surface is determined by focusing on an etched portion of the first slide.

12. The system of claim 1, wherein the sled is configured to cause the second slide to move under the pivot point, and the sled further comprises an aperture configured to allow a pin to be positioned below the second slide to further regulate motion of the second slide.

13. The system of claim 1, wherein the second slide is configured to provide contact pressure on the first slide for smearing the sample.
